I talked with Issac's father, Hickey, this morning for a bit. He confirmed that they will be in Columbia this weekend for the game. He said there is nothing specifically they are looking at on this trip compared to previous visits, "just want to get around Columbia a little more" was his reply.
Obviously, it's a good sign that Thompson and his family are visiting Missouri again the week before he announcing his decision - which will be Friday, December 4th. That shows that the Tigers are real contenders here.
His father also told me that a trip to Arkansas could be in the works to at some point next week, but that hasn't been set in stone yet. So, it appears the Razorbacks along with Michigan and perhaps Texas to a lesser degree are the other contenders here.
**P.S. Let's try our best to not let this Isaac Thompson thread go off the rails and into the realm of deplorable message board finger-pointing**
